Seeed Studio XIAO nRF52840 2: Zephyr, nRF Connect SDK, GPIO and UART

Seeed Studio XIAO nRF52840: Zephyr, nRF Connect SDK, GPIO and UART

The XIAO BLE is an inexpensive developer board from Seeed and is equipped with the Nordic Semiconductor SoC nRF52840. It can be programmed with the nRF Connect SDK. It supports BLE and also OpenThread via the RTOS Zephyr. The Xiao has an Arduino bootloader and the firmware in uf2 format can be easily transferred to the chip using drag and drop. In this video, we demonstrate programming a GPIO pin to make an LED blink. We then proceed to program the UART interface (uart0) and establish communication with a PC terminal program using a USB-UART bridge (FTDI FT232).
